Simultaneously edit a document with other authors
When you collaborate with other authors to create a document, you can save time by simultaneously editing the document, instead of doing this separately. To edit the document at the same time, each author opens the file from a common location on a server.
You can simultaneously edit documents in the .docx file format that are located on Windows Live SkyDrive or a server that has Microsoft SharePoint Server 2010 installed. To work with SharePoint in Office for Mac, you have to have Microsoft Office for Mac Home and Business 2011, Microsoft Office for Mac Academic 2011, or Microsoft Office for Mac Standard 2011.
With the document open on your computer, you can see who else is editing the document, who is editing a specific paragraph, and when updates from other authors are available on the server.
Other author currently editing the document
All authors currently editing the document
Changes from other authors available on the server
When you save your changes to the server, any updates from other authors are automatically refreshed in the document. Updates from other authors are refreshed automatically only if they don't conflict with changes that you made. If you and another author both change the same item, then a conflict may occur. If a conflict occurs when you save the document, you are prompted to review the conflict and accept or reject the change.
Do any of the following:
Save a document to a SharePoint site
Save a document to a Windows Live SkyDrive
Open a document that is located on a SharePoint site
Open a document that is located on a Windows Live SkyDrive
See who else is editing a document
Save and refresh a document that has updates
Review and accept changes from other authors
